Abstract:
In order to solve the electromagnetic problems on the large multi-branch domains, the decomposition projective method(DPM)is generalized for multi-subspaces in this paper. Furthermore multi-parameters are designed for DPM, which is called the fast DPM(FDPM), and the convergence ratio of the above algorithm is greatly increased. The examples show that the iterative number of the FDPM with optimal parameters decreases much more, which is less than one third of the DPM iteration number. After studying the algorithm of FPDM, the representations of the optimal parameters are also given. Finally the applying efficiency of FPDM is raised.
本文针对大型多枝区域上的电磁场问题, 将投影分解法推广到向多个空间投影的情形, 并设计了带有多个参数的快速算法, 大大提高了算法收敛速度, 实际算例表明迭代次数不到原来的三分之一.通过对所取参数的分析, 给出了其最优值表达式, 使得该算法具有很好的实用性.
